JLM is also a compliance centre, meaning that they can draw from resources, the history of the car until it left Japan. Mizo at JLM used to work for Nissan Japan but you'll probably require one of the other guys to translate what he's saying. Compression and leakdown tests will be done, and whilst it's up on a hoist you can check bushes, rust, seepage etc. Latching onto JLM is a wise move.
